I wish this helpful for you Enabling Build Automatically is not your answer. There is something you've changed.. maybe a call to your integrated library or something linking outside resources.

In Android development the generated resource files many times account for mistakes in Builds and the need to clean/build.

Maven clean + build causes project in Eclipse to show errors until clean in Eclipse
I wish this helpful for you We have had the exact same problem a while ago. We had more than 20 projects giving the same kind of error.

this one helps. Specifically in my case, the following sequence of actions worked: Project -> uncheck Build Automatically [accept incoming changes] if applies Project -> clean Run -> Run As -> Maven clean Run -> Run As -> Maven install Project -> check build automatically if errors on Problems Tab appear: select all projects, Refresh F5 if still errors: delete errors manually on Problems Tab (it might be that Eclipse has not updated the dependencies, etc.) select all projects, Refresh F5
